A Big Win for SpaceX

He may be the Charles Lindburgh of our day.  Elon Musk - born in South Africa to a Canadian mother.  Traveled to Canada, became a Canadian citizen, studied in Canada before moving on to the US where he is now an American citizen.  He has five sons by his Canadian first wife, twins followed by triplets, all of whom now live in the States.

Elon Musk broke into the big leagues by creating PayPal and growing it to the point where, in 2002, Ebay bought it for 1.5-billion dollars in stock.

Musk went on to found Tesla Motors and then made the company's electric battery technology freely available to competitors to encourage production of electric cars.  From there Musk went on to devise the concept for Solar City, operated by his cousins, which has become the largest provider of solar power systems in the US.  Solar City was springboarded on battery technologies developed for Tesla.

What might be the most ambitious venture Musk has undertaken, however, is SpaceX or Space Exploration Technologies.  Using his own money, Musk recruited experts from NASA and American aerospace giants to develop his own launch vehicles and capsules.  A breakthrough moment came in April with the successful docking of a SpaceX Dragon cargo capsule with the International Space Station.


Since the end of the Space Shuttle programme, NASA has relied on Russian Soyuz flights to ferry astronauts to the ISS.  However, with the breakdown of US-Russian relations over the Ukraine troubles, NASA has decided to go with a US alternative.

Until recently the contract would have gone to a major US defence contractor. SpaceX got into a similar situation with the Pentagon that ended when it sued to be allowed to compete.  NASA apparently got the message and this time, it split its space station shuttle contract between Boeing  ($4.2-billion) and SpaceX ($2.9-billion).  

Boeing's 5-seat capsule will compete with the 7-seat, Dragon-2 of SpaceX.  

Crew Seating Configuration

If I had to choose, I'd rather go on the Dragon 2.  The capsule comes with a launch escape system, eight rocket motors generating 120,000 lbs. of thrust that will speed the capsule to safety in case of an emergency any time between when the occupants strap in on the launch pad and when they reach orbit.


The system also allows the capsule to effect a soft landing on a prepared pad instead of having to resort to the standard US water landing.


Musk's next goal?  Mars.

Who Wants to Be the Piers Morgan of Mars?


Inventor/entrepreneur Elon Musk says he wants to travel to Mars.  He's young enough that he might manage to do that unless he comes to his senses and thinks better of it.  Still there are thousands lining up for a chance to make the one-way trip.

Some say it is possible (or within a decade or two will be) to land a small human expedition on Mars.  We could pre-deploy all the life support stuff - food, water, building materials, fuel, oxygen, etc.

There will be plenty of challenges - exposure to radiation, the Martian environment, just landing safely.  Scientists seem optimistic of their abilities to work around those.

Yet there's one Achilles' Heel that science can't engineer out - human attention span.  Oh it'd be great to watch them land and we'd be enthusiastic little voyeurs glued to the screen to see  them get organized and sheltered.  But then what?  What do they do for a second act?   There is no second act.  After act one is completed, it's essentially a very, very long death watch. 

We might place bets on who would go first and what would get them but even then we'd grow impatient.  It would be like one of those reality shows where you're waiting, month after month, for fate to vote somebody off the island.

It's more than possible that we could get frustrated with, even resentful of these new Martians.  They won't have much to offer us but we'll still have to shell out billions of dollars to keep these extra-terrestrials in toilet paper and shampoo until death do them part.   At some point, some bright light is going to run the numbers and tell us that we could be saving thousands of kids' lives for what we're forking out on a pair of space wastrels who, in any case, knew they were going to Mars to die.  Why should innocent children die so those distant loafers, who aren't coming back anyway, can drag out their own demise?

It's a safe bet that our Martian voyagers would one day receive a message that their regular supply ships won't be all that regular any longer and that they should really focus on stretching out what they've got on hand - well, forever.

Piers Morgan lasted three years on CNN.  Could our Martian envoys expect to do much better?
